SHANK-LASTING TOOL.

SPECIFICATION forming part of Letters Patent No. 273,283, dated March 6,1883.

' Application filed November 21, 1882. (No model.)

To all whom 1t may concern Beit known that we, ANDREW JACKSON andWILLIAM BRINTON J EFFERIS, citizens of the United States, residing atXenia, in the county of Clay and State of Illinois, have inventedcertain new and useful Improvements in Tools for LastingBoots and Shoes;and we do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawing, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to implements for lasting boots and shoes in theshank; and its object is to enable the operation of shank-lasting to bedone in a speedy, convenient, simple, even, close, and firm manner, withboth sides of the shank drawn in at the same time in like proportion,the tool itself possessing a high degree of power, strength, anddurability relatively to its simplicity and cost.

The accompanying drawing gives an up right perspective view of ourshank-laster with its double clamp and one of its lever or handle clampsspread partly open.

The tool may be made of iron, steel, or any other suitable metal.

A A are the two arms of a clamp connected at top by a hinge and rivet,which allowthem to be spread or closed at pleasure. The lower tenon isbeveled off and formed into corrugations, as shown at I), thesecorrugations fitting closely into those of the clamping-arms heretoforedescribed. The lower part of each lever is broadened and flattened togive a firm grasp to the hand of the workman.

The mode of operation consists in the workmans placing the boot or shoeto be lasted upon his knees, bottom upward, and heel against the breast.The lasting-tool is straddled over the boot, the ends or edges of theleather to be lasted placed in the corrugated jaws, and the leverspressed by the hands toward each other, and so held by the legs of theworkman while the lasting-tacks are driven in. If preferred, the ends ofthe compressed lovers may be caught and held in the teeth of a long fiatratchet formed in or attached to the workmans sitting or standing bench,near the edge, and the ends of the levers may be beveled and. notched,as shown at c c, to prevent lengthwise or sidewise slipping in anyratchet projecting above the surface of the work-bench.

Having thus described our invention, what we claim to be new and useful,and desire to secure by Letters Patent, isv A lasting-tool for boots andshoes, consisting of thejaws A A, hinged at the top, and pro vided withcorrugations a, a and the mortises a, and having pivotally connectedthereto, as described, the outwardly-curved hand-levers B B, providedwith the tenons I), corrugations b, and notched beveled edges 0 c, allsubstantially as and for the purpose set forth.

In testimony whereof We affix our signatures in presence of twowitnesses.
